如何在自己的主頁上使用PHP
Jun 08, 2016 pm 05:33 PM1.PHP是什么?
PHP,一種新型的CGI程序編寫語言,易學(xué)易用,運行速度快,可以方便快捷地編寫出功能強大,運行速度快,并可同時運行于Windows、Unix、Linux 平臺的Web后臺程序,內(nèi)置了對文件上傳、密碼認(rèn)證、Cookies 操作、郵件收發(fā)、 動態(tài)GIF生成等功能,PHP直接為很多數(shù)據(jù)庫提供原本的連接,包括Oracle,Sybase,Postgres,Mysql,Informix,Dbase,Solid,Access 等 ,完全支持ODBC接口。PHP4.0提供了更多web server的支持,例如Zeus, Netscape Enterprise, Apache Win32 module。
(上面這段話是網(wǎng)上轉(zhuǎn)來的,是不是已經(jīng)看暈了……)
總之,我的理解,PHP是一種動態(tài)WEB腳本語言。就這么簡單啦.... 比如我這里的論壇系統(tǒng),全部都是php程序的。
2.到哪里尋找PHP源代碼?
我們當(dāng)然不能指望每個人都能獨立編寫PHP程序。作為普通的網(wǎng)頁制作者,我們可以使用現(xiàn)成的PHP程序。很多站點都提供免費的PHP源代碼下載。
其中,最有名的就是中國站長站(http://www.chinaz.com/)。從這類站點上,我們可以找到我們需要的程序源代碼。
3.如何使用下載的PHP源代碼?
源代碼下載下來了,有人就不知道該怎么用。下面我分步來說明。
?。?)查看代碼使用說明:
一般下載來的程序,都有readme文件,告訴你如何安裝使用本程序。有些程序只需將所有文件上傳,就可以使用。有些程序需要運行install.php進(jìn)行安裝,這要看具體情況。
(2)調(diào)試程序有兩種方法。一種是在自己的機(jī)器上構(gòu)建一個本地調(diào)試環(huán)境進(jìn)行調(diào)試,另一種是將程序上傳到主頁服務(wù)器上進(jìn)行調(diào)試。
本地調(diào)試,一般使用apache,php和mysql三種軟件構(gòu)建本地調(diào)試環(huán)境。由于安裝這三個軟件,需要修改注冊表和其他很多設(shè)置,對初學(xué)者來說太過復(fù)雜,我推薦使用phptraid這個軟件(下載地址:

To safely handle PHP file uploads, you need to verify the source and type, control the file name and path, set server restrictions, and process media files twice. 1. Verify the upload source to prevent CSRF through token and detect the real MIME type through finfo_file using whitelist control; 2. Rename the file to a random string and determine the extension to store it in a non-Web directory according to the detection type; 3. PHP configuration limits the upload size and temporary directory Nginx/Apache prohibits access to the upload directory; 4. The GD library resaves the pictures to clear potential malicious data.

If the second monitor is not recognized by Windows, first check whether the cable and interface are normal, try to replace the HDMI, DP or VGA cable, confirm the plug-in video output port, and test different interfaces to eliminate compatibility issues; then verify the monitor power and input source settings, and connect the monitor separately to test whether it can be recognized; then enter the Windows display settings and click the "Detection" button, or use Win P to switch the display mode, and update the graphics card driver at the same time; finally check the graphics card specifications to confirm whether it supports multi-screen output to avoid exceeding its maximum output capability.

Character set and sorting rules issues are common when cross-platform migration or multi-person development, resulting in garbled code or inconsistent query. There are three core solutions: First, check and unify the character set of database, table, and fields to utf8mb4, view through SHOWCREATEDATABASE/TABLE, and modify it with ALTER statement; second, specify the utf8mb4 character set when the client connects, and set it in connection parameters or execute SETNAMES; third, select the sorting rules reasonably, and recommend using utf8mb4_unicode_ci to ensure the accuracy of comparison and sorting, and specify or modify it through ALTER when building the library and table.

When you encounter the "DefaultGatewayisNotAvailable" prompt, it means that the computer cannot connect to the router or does not obtain the network address correctly. 1. First, restart the router and computer, wait for the router to fully start before trying to connect; 2. Check whether the IP address is set to automatically obtain, enter the network attribute to ensure that "Automatically obtain IP address" and "Automatically obtain DNS server address" are selected; 3. Run ipconfig/release and ipconfig/renew through the command prompt to release and re-acquire the IP address, and execute the netsh command to reset the network components if necessary; 4. Check the wireless network card driver, update or reinstall the driver to ensure that it works normally.

MySQL supports transaction processing, and uses the InnoDB storage engine to ensure data consistency and integrity. 1. Transactions are a set of SQL operations, either all succeed or all fail to roll back; 2. ACID attributes include atomicity, consistency, isolation and persistence; 3. The statements that manually control transactions are STARTTRANSACTION, COMMIT and ROLLBACK; 4. The four isolation levels include read not committed, read submitted, repeatable read and serialization; 5. Use transactions correctly to avoid long-term operation, turn off automatic commits, and reasonably handle locks and exceptions. Through these mechanisms, MySQL can achieve high reliability and concurrent control.

The most direct way to find the last occurrence of a substring in PHP is to use the strrpos() function. 1. Use strrpos() function to directly obtain the index of the last occurrence of the substring in the main string. If it is not found, it returns false. The syntax is strrpos($haystack,$needle,$offset=0). 2. If you need to ignore case, you can use the strripos() function to implement case-insensitive search. 3. For multi-byte characters such as Chinese, the mb_strrpos() function in the mbstring extension should be used to ensure that the character position is returned instead of the byte position. 4. Note that strrpos() returns f

To design a reliable MySQL backup solution, 1. First, clarify RTO and RPO indicators, and determine the backup frequency and method based on the acceptable downtime and data loss range of the business; 2. Adopt a hybrid backup strategy, combining logical backup (such as mysqldump), physical backup (such as PerconaXtraBackup) and binary log (binlog), to achieve rapid recovery and minimum data loss; 3. Test the recovery process regularly to ensure the effectiveness of the backup and be familiar with the recovery operations; 4. Pay attention to storage security, including off-site storage, encryption protection, version retention policy and backup task monitoring.
